Messages not uploaded with MSN

A curious issue has arisen in the last month. Up until then I could post or answer a message with MSN as my platform with no problems. In the last month I can write a message or response but, when I hit Preview or Send, it says there is no content. This does not happen with IE. Supposedly both IE and MSN use the same IE platform. No changes or upgrades to MSN. Have run all the Malware programs etc.



Any suggestions? I know I can continue to use IE but I'd like to solve this.



Thanks,
